The Cave of Summons is an optional dungeon located on the Moon, accessible only after obtaining the Lunar Whale. This challenging area is home to powerful enemies and, more importantly, two of Rydia's most potent summons: Bahamut and Leviathan. To access Bahamut, you must first defeat him in battle. He is a formidable foe, capable of casting Mega Flare, which deals massive non-elemental damage to your entire party. Ensure your party is at a high level (around 60+) and equipped with the best available gear. Magic defense is crucial. Leviathan is found deeper within the cave and requires a separate encounter. The dungeon itself is a maze, so be prepared for numerous random encounters. The rewards, however, are well worth the effort, as Bahamut and Leviathan are invaluable additions to Rydia's arsenal, especially for the final battles.
